CROSS REFERENCE TO RELATED APPLICATION

This application claims priority from and benefit of U.S. Non-Provisional application Ser. No. 14/825,377, filed Aug. 13, 2015, entitled “Application-Based Dynamic Heterogeneous Many-Core Systems and Methods,” which is hereby incorporated by reference in its entirety for all purposes.

FIELD OF THE INVENTION

This invention relates to application-based dynamic heterogeneous many-core systems for application acceleration.

BACKGROUND OF THE INVENTION

Application and tasks implemented on an integrated circuit can be accelerated by using different processing mechanisms such as a many-core processing system, which is a large scale multi-CPU parallel processing system having multiple processing cores. Applications can then be processed by more than one core processor in parallel so as to improve processing speed. Typical acceleration operation using such a many-core structure requires significant investment in software and soft logic co-design. High-level design (HLD) techniques can partially bridge the software-to-logic design gap but typically require a system with fixed cores that are dedicated to serve certain application needs.

For example, some fixed circuit designs can provide a homogeneous or fixed heterogeneous many-core platform, but these designs are non-scalable. Some reprogrammable systems can offer scalable designs to add processing cores on an as-needed basis, expanded with the potential building of on-demand application-specific high-performance platform with mixed heterogeneous architecture of acceleration processing node, e.g., through a reprogrammable FPGA. These scalable solutions, however, may not cater to the scenario when a custom software solution is needed to manage the core in a dynamic system.

Other solutions and designs for application acceleration that exist in the industry can include many-core communications application programming interface (MCAPI), message passing interface (MPI), and open multi-processing (OpenMP). All of these systems assume a fixed many-core system that focuses on communication between known cores such that specific distributed tasks can be mapped to known fixed cores, instead of addressing the needs of managing a dynamic many-core system design. Thus, these systems are incapable of dynamically changing the available parallel processing cores for application acceleration.

SUMMARY OF THE INVENTION

In accordance with embodiments of the present invention, methods and systems for dynamic mapping of different parallel processing cores based on application needs are introduced.

Therefore, in accordance with embodiments of the present invention there is provided a method for dynamically configuring multiple processors based on needs of applications. The method includes receiving, from an application, an acceleration request message including a task to be accelerated. The method further includes determining a type of the task and searching a database of available accelerators to dynamically select a first accelerator based on the type of the task. The method further includes sending the acceleration request message to a first acceleration interface located at a configurable processing circuit. The first acceleration interface sends the acceleration request message to a first accelerator, and the first accelerator accelerates the task upon receipt of the acceleration request message.

In accordance with another embodiment of the present invention there is provided a heterogeneous many-core acceleration (HMA) system for dynamically configuring multiple cores based on needs of applications. The system includes a processor subsystem including a queue management unit and a dispatcher. The queue management unit receives, from an application, an acceleration request message including a task to be accelerated, and determines a type of the task. The dispatcher searches a database of available accelerators based on the type of the task to dynamically select a first accelerator based on the type of the task. The system further includes a configurable processing circuit. The configurable processing circuit includes a first acceleration interface that receives the acceleration request message from the dispatcher and sends the acceleration request message to the first accelerator when the first accelerator is available, and a first accelerator that accelerates the task upon receipt of the acceleration request message.

DETAILED DESCRIPTION OF THE INVENTION

Unless otherwise indicated, the discussion that follows will be based on an example of a programmable integrated circuit device such as a Field-Programmable Gate Array (FPGA). However, it should be noted that the subject matter disclosed herein may be used in any kind of fixed or programmable device, including, but not limited to, an application-specific integrated circuit (ASIC).

In some embodiments of the invention, the discussion that follows describes a heterogeneous core management system that includes a queue manager that stores application tasks, a dispatcher that abstracts the software-hardware communication channel, and an accelerator interface that receives and/or transmits application-constructed acceleration messages. The heterogeneous core management system can enable software layers to dynamically configure a set of parallel processing cores based on the needs of the application. The software layers may also rely on communication to a set of predefined hardware building blocks (with the system memory management unit (SMMU)) that can be dynamically combined with soft processing cores for acceleration. Software designs can then focus on solving application problems within a dynamic many-core system through self-sustained dynamic many-core system management.

In some embodiments of the invention, the discussion that follows describes a system that provides application acceleration/processing without the need to manage the underlying hardware. This feature can be realized through enabling hardware-management-system-agnostic application abstraction layers. The described system can enable application-driven parallel processing cores where the architecture of the core is defined by the needs of the application. The described system further allows dynamic load-balancing for a set of predefined parallel processing cores across the applications, and enables general purpose processing cores, general purpose operating systems (OS) and fixed function hardware (HW) interoperability.

In some embodiments of the invention, the described system throughout the discussion in the instant application can be implemented on a configurable processing circuit that contains an array of programmable logic blocks. The array of programmable logic blocks can be configured and programmed to be interconnected by reconfigurable interconnect units. The programmable logic blocks can be configured to host various processors, or other logic components to perform various logic, combinational or processing functions. For example, various processors such as a general-purpose processor, a specialized processor, or other soft microprocessors can be embedded or synthesized on the configurable processing circuit, and the configurable processing circuit can be configured or programmed to dynamically select and/or engage one or more of the processors, and/or virtually add or remove processors using logic synthesis, based on application needs, e.g., application acceleration request messages sent by applications. As the processors or soft processors are dynamically chosen or synthesized, no pre-defined or pre-fixed relationship between an application and a specific processor or soft processor is required.

FIG. 1 shows an example block diagram illustrating aspects of handling application acceleration requests at a Heterogeneous Many-Core Acceleration (HMA) system. As shown in FIG. 1, various software applications 105 a-n may be running on a computing device and/or system, such as but not limited to a personal computer, a workstation, a server, and/or the like. The various software applications 105 a-n can send acceleration messages 107 a-n to a system processor to accelerate a task. For example, an email application 105 a can send an acceleration message 107 a for an email “send/receive” request; a MP3 player 105 b can send an acceleration message 107 b to request MP3 encoding/decoding; or a gaming application 105 n can send an acceleration message 107 n for real-time data encryption/decryption, and/or the like. An HMA system 110, e.g., located at a workstation, a server, and/or the like, can receive and process such acceleration messages 107 a-n. The HMA system 110 includes multiple processors 111 a-n, such as a general-purpose processor, a special-purpose processor, and/or the like to process the acceleration messages 107 a-n.

FIG. 2 shows an example block diagram illustrating an example architecture of an HMA system. The HMA system 200 may include a hard processor 201 that may be the primary core of the system, and a configurable processing circuit such as an FPGA 202. The hard processor 201 may include a queue manager 203 for application message queue management and a dispatcher 204 to handle requests to HMA software dispatching unit. The queue manager 203 can manage software message queues storing software messages, which are, for example, constructed by multicore communications application program interface (MCAPI) software layers. The dispatcher 204 can serve as a message gateway between applications and accelerators, e.g., a software resource management unit that keeps track of HMA status, and map software requests to functions offered by HMA.

The FPGA 202 includes a plurality of HMA interfaces 205 a-e, which are the hardware interfaces for the dispatcher 204 to distribute work to accelerator engines that offer similar functions with the distributed work. The HMA interfaces 205 a-e may parse and route tasks to available accelerators, e.g., acting as a hardware resource management unit that keeps track of individual accelerator engine status. The FPGA may include a variety of accelerators such as general-purpose embedded processors 206 or more specialized embedded processors 207, Open Computing Language (OpenCL) processors 208, application-specific instruction-set (ASIP) processors 209, fixed function (FF) blocks 211, and/or the like. For circuit design purposes, each of the accelerators can be color-coded or identified by any other kind of unique identification in a circuit map such that the circuit map can illustrate different accelerators. The accelerators can be registered for a type of the HMA interface based on a type of the accelerator. For example, the HMA interfaces 205 a-e may each interface with a color code of the accelerators, as shown in the matching patterns of blocks 205 a-e and 206, 207, 208, 209, 211, respectively.

FIG. 3 shows an example flow diagram illustrating data flows within the HMA system shown in FIG. 2 for the queue manager 203 and dispatcher 204 to enable a single application access interface. Software applications can decide functions that need to be accelerated, and then construct the acceleration messages 215 a-c from different applications. The application acceleration messages 215 a-c can then be sent to the queue manager 203 (e.g., as shown at arrows 301), the software message controlling and queuing unit that receives, responds to, or queues up application acceleration messages 215 a-c. Each queue in the queue manager 203 is identified with and corresponds to its acceleration function. Examples of acceleration functions can include, but are not limited to, encryption, description, MP3 encoding, MP3 decoding, and/or the like. The function could also be OpenCL kernel-defined.

In a further implementation, a closely distributed core processor 230 may share the queue manager 203 in the hard processor 201. For example, the distributed core processor 230 can connect with the queue manager 203 via a shared system bus 220 (e.g., peripheral component interconnect (PCI), peripheral component interconnect express (PCIe), advanced microcontroller bus architecture (AMBA), network interface, etc.) and send application acceleration messages 215 d received at the distributed core 230 to the queue manager 203 at hard processor 201.

At arrow 302, the dispatcher 204 takes the software message queue in the queue manager 203 and dispatches each acceleration message to a matching acceleration function accelerator interface (e.g., at arrow 303) based on availability of the accelerator. For example, application acceleration messages 215 a may be dispatched to HMA interface 205 a; application acceleration messages 215 b may be dispatched to HMA interface 205 b; application acceleration messages 215 c may be dispatched to HMA interface 205 c; and application acceleration messages 215 d may be dispatched to HMA interface 205 d, as shown in the matching patterns of the blocks 205 a-d and 215 a-d, respectively.

The dispatcher 204 may check an internal database for available accelerators and dispatch the message to accelerator interfaces 205 a-e. The accelerator interfaces 205 a-e may then notify available processing nodes 206 a-b, 208 a, 209 a and 211 a to pick up the message (e.g., as shown at arrows 304 a-d). For example, HMA interface 205 a may send a message 304 a to the embedded processors 206 a or 206 b for acceleration, depending on availability of the processors 206 a-b.

As shown in FIG. 3, the software infrastructure/layers include the application-constructed acceleration messages 215 a-c, the queue manager 203 and the dispatcher 204 that abstracts the communication channel to dynamically configurable set of parallel processing cores based on the need of the application. Thus, software design can focus on solving application problems rather than optimizing software for specific hardware accelerators, and flexible acceleration cores can be dynamically constructed/deconstructed based on the application need using the available FPGA hardware. The acceleration/processing load distribution can be abstracted from application software.

FIG. 4 shows an example flow diagram illustrating data flows within the HMA system shown in FIG. 2 for virtual expansion of accelerators with Partial Reconfiguration (PR). When an acceleration message 216 from a new application is sent to the queue manager 203, e.g., at 401, the queue manager 203 may not recognize a type of the function requested by the acceleration message 216, or the requested function may not be processed at the available accelerators. In that case, the dispatcher 204 may send the acceleration message to a PR application module 410 (e.g., at 402), which may dynamically (e.g., based on the needs of the new acceleration message from the new application 216) reconfigure the logic fabric of the FPGA 202 to synthesize a soft core processor based on the needs of the new acceleration message while the remaining logic continues to operate unperturbed. For example, PR application 410 may add or synthesize an HMA interface 205 f with new accelerators digital signal processors (DSP) 212 a-b reconfigured on the FPGA 202, e.g., at 403. The dispatcher 204 may then send the acceleration message 216 to the newly configured HMA interface 205 f for processing, e.g., at 404. Alternatively, the PR application 410 may reconfigure an additional FF 211 d (if the type of acceleration function matches) that can register with existing HMA interface 205 e; and the FF 211 d can be used to process the new acceleration message 216.

Thus, the capacity of an FPGA fabric for hardware acceleration needs can be expanded by the virtual expansion of accelerators, without enlarging the physical size of the FPGA fabric. For example, dissimilar processing engines (e.g. ASIP, FF, other embedded processors, etc.) can be virtually added or removed from the FPGA 202 using partial logic configuration without explicit software handling or code modifications.

FIG. 5 shows an example logic flow diagram illustrating aspects of application-based dynamic configuration of application acceleration in the HMA systems shown in FIGS. 2-4. Starting with 501, an HMA system may receive an acceleration message from an application, e.g., which may be queued up at a queue manager 203 in FIG. 2. The HMA system may then determine a type of the acceleration function at 503, e.g., based on the originating application type, task type, estimated processing time, estimated resource requirement, and/or the like. The HMA system may then search a database of available accelerators in the HMA system based on the function type at 505. When there are available accelerators at 507, the HMA system may send the acceleration message to the available accelerator at 511, which may in turn process the acceleration message at 513 to accelerate the respective application task.

When no accelerator is available at 507, the HMA system may wait for the next available accelerator at 516. Or alternatively and optionally, the HMA system may implement virtual expansion of accelerators with partial reconfiguration (PR) at 517 (as discussed in FIG. 4) such that a new accelerator via PR expansion can process the acceleration message at 518. The new accelerator may then return the computed result (e.g., the acceleration result, etc.) to the application upon completing the acceleration or computation, at 519.

FIG. 6 shows an example block diagram illustrating a hardware architecture of the HMA hardware subsystem 600. The HMA subsystem 600 can be built as a system on a programmable chip (SOPC). The queue manager 203 and/or the dispatcher 204 software can run on a processor subsystem 630. The processor subsystem 630 can act as the main software-hardware interface for the HMA subsystem 600, and communicate with an optional direct memory access (DMA) unit 611 for movement of data from the system memory to be processed if needed. The queue manager 203 and/or the dispatcher 204 software can communicate with the various accelerator blocks 612, 613, 614 and 615 of the HMA via a memory mapped bus 620.

Accelerators 612-615 can be built from HMA building blocks combined with FPGA soft fabric that can be used to construct acceleration engines. The HMA building blocks provide software-hardware interface and memory interface, which can include external memory interfaces 606 a-c (EMIF) that interface the SMMU 610 and external memory unit such as random-access memory (RAM) units 605 a-c. The software-hardware interface including the memory-mapped system bus 620 and the SMMU 610 may virtualize selective accesses to system memory to reduce physical data movement even across different physical memories. For example, data movement throughout the system can be realized without physically moving the data, e.g., by simply remapping the memory map within the SMMU 610 to virtually move data in system memory. In this way, power consumption can be reduced due to processing data movement when switching from one core to another. The processing memory can be spread for the HMA systems to be distributed across different physical memory. Chained processing/acceleration of raw data via multiple processing/acceleration engines can thus be realized (e.g. sequence of rendering an image), and system memory protection policies can be enforced by restricting certain applications from accessing portions of the accelerator/core memory.

The SMMU 610 can virtualize selective accesses to system memory (e.g., RAM 605 a-c) and may help to reduce physical data movement, e.g., by allowing physical memory to be scattered (even across multiple physical memory interfaces 606 a-c) and abstracting system memory addressing, enforcing memory protection/integrity, and/or the like. In this case, as the HMA system can be partially reconfigured (discussed in connection with FIG. 4), the SMMU 610 can implement selective access to system memory such that only data related to the partial reconfiguration needs to be loaded or transmitted, without loading an entire program of the FPGA soft fabric.

FIGS. 7-8 show example block diagrams illustrating a hardware architecture of the HMA components (e.g., HMA building blocks). As shown in FIG. 7, an HMA building block can have columns of high-speed serial interfaces (HSSI) 701 a-b, and parallel EMIF input/output 703 a-b to communicate with accelerators such as FF 711 a-b, ASIP 712 a-b, embedded processor 713, and/or the like. A heterogeneous acceleration building block 705, which can be a hardware component that controls the accelerators, as further illustrated in FIG. 8, can be placed between layers of accelerators, as shown in FIG. 7.

The HMA subsystem may have a column-based implementation for data stores, and communicate with initiators via ring queue descriptors. For example, initiators (e.g., an application acceleration requester, etc.) can build ring queue request descriptors and initiate HMA via a configuration and status register (CSR). The initiators can then be informed of acceleration completion via interrupt (or other mechanisms).

FIG. 8 shows the heterogeneous acceleration (HA) building block structure and its interaction with an FPGA fabric (e.g., accelerator engines 715, local memory 716, etc.). As shown in FIG. 8, the set of HMA hardware building blocks 705 including the bus interface (and CSR) 717, a parser 718, a DMA unit 720, and a scheduler 719, can be dynamically “glued” with soft processing engines 715 constructed on the FPGA core fabric to form the set of parallel processing/acceleration cores. In this way, any processing/acceleration function can communicate with the accelerator engines via the software infrastructure/layers defined. Software-controlled load balancing can then be done dynamically by abstracting the processing engines from the communication medium.

The bus interface 717 (and CSR) may interface with memory mapped bus 620 and contain the CSR as software interface. The DMA 720 and the parser 718 may communicate with the SMMU 610 and EMIF 606 a-c (also shown in FIG. 6) to load data and update status information. The DMA 720 and the parser 718 may also communicate with local memory 716 to retrieve or store application tasks and/or acceleration messages. For example, the parser 718 may traverse request descriptors and update the status of the tasks when done; and the DMA 720 may pull processing data from SMMU 610 (or via the EMIF 606 a-c) and deposit processed data to SMMU 610. The scheduler 719 may initiate engine acceleration based on descriptors and distributes the workload across multiple acceleration engines 715.

Because the FPGA fabric (e.g., including the accelerator engines 715 and local memory 716) can be dynamically “glued” or combined with an HMA building block 705, a larger than physically available FPGA fabric for hardware acceleration needs can be realized. The dynamic matching/configuration of accelerator engines 715 can also allow construction/deconstruction of dissimilar processing engines (e.g. ASIP, FF, other embedded processors, etc.) without affecting application software function.

FIG. 9 presents a cross section of a magnetic data storage medium 900 which can be encoded with a machine executable program that can be carried out by systems such as a personal computer, or other computer or similar device, for configuring FPGAs or other programmable logic devices (PLDs) for use in systems as described above. Medium 900 can be a floppy diskette or hard disk, or magnetic tape, having a suitable substrate 901, which may be conventional, and a suitable coating 902, which may be conventional, on one or both sides, containing magnetic domains (not visible) whose polarity or orientation can be altered magnetically. Except in the case where it is magnetic tape, medium 900 may also have an opening (not shown) for receiving the spindle of a disk drive or other data storage device.

The magnetic domains of coating 902 of medium 900 are polarized or oriented so as to encode, in manner which may be conventional, a machine-executable program, for execution by a programming system such as a personal computer or other computer or similar system, having a socket or peripheral attachment into which the PLD to be programmed may be inserted, to configure appropriate portions of the PLD, including its specialized processing blocks, if any, in accordance with the invention.

FIG. 10 shows a cross section of an optically-readable data storage medium 1010 which also can be encoded with such a machine-executable program, which can be carried out by systems such as the aforementioned personal computer, or other computer or similar device. Medium 1010 can be a conventional compact disk read-only memory (CD-ROM) or digital video disk read-only memory (DVD-ROM) or a rewriteable medium such as a CD-R, CD-RW, DVD-R, DVD-RW, DVD+R, DVD+RW, or DVD-RAM or a magneto-optical disk which is optically readable and magneto-optically rewriteable. Medium 1010 preferably has a suitable substrate 1011, which may be conventional, and a suitable coating 1012, which may be conventional, usually on one or both sides of substrate 1011.

In the case of a CD-based or DVD-based medium, as is well known, coating 1012 is reflective and is impressed with a plurality of pits 1013, arranged on one or more layers, to encode the machine-executable program. The arrangement of pits is read by reflecting laser light off the surface of coating 1012. A protective coating 1014, which preferably is substantially transparent, is provided on top of coating 1012.

In the case of magneto-optical disk, as is well known, coating 1012 has no pits 1013, but has a plurality of magnetic domains whose polarity or orientation can be changed magnetically when heated above a certain temperature, as by a laser (not shown). The orientation of the domains can be read by measuring the polarization of laser light reflected from coating 1012. The arrangement of the domains encodes the program as described above.

For example, various elements of this invention can be provided on a PLD in any desired number and/or arrangement.
